16.My DSL service’s PPPoE is always disconnecting.
PPPoE is not actually a dedicated or always-on connection. The DSL ISP can disconnect the service after a
period of inactivity, just like a normal phone dial-up connection to the Internet.
•
There is a setup option to “keep alive” the connection.
This may not always work, so you may need to re-
establish connection periodically.
1.
To connect to the Router, go to the web browser, and enter http://192.168.1.1 or the IP address of the
Router.
2.
Enter the password, if asked. (The default password is admin.)
3.
On the Setup screen, select the option
Keep Alive
, and set the Redial Period option at 20 (seconds).
4.
Click the
Save Settings
button.
5.
Click the
Status
tab, and click the
Connect
button.
6.
You may see the login status display as Connecting. Press the F5 key to refresh the screen, until you
see the login status display as Connected.
•
Click the
Save Settings
button to continue.
•
If the connection is lost again, follow steps 1- 6 to re-establish connection.
17.I can’t access my e-mail, web or I am getting corrupted data from the Internet.
The Maximum Transmission Unit (MTU) setting may need to be adjusted. By default, the MTU is set at 1500.
For most DSL users, it is strongly recommended to use MTU 1492.
•
If you are having some difficulties, perform the following steps:
1.
To connect to the Router, go to the web browser, and enter http://192.168.1.1 or the IP address of the
Router.
2.
Enter the password, if asked. (The default password is admin.)

18.The Power LED keeps flashing.
The Power LED flashes when the device is first powered up. Meantime, the system will boot up itself and
check for proper operation. After finishing the checking procedure, the LED stays solid to show that the
system is working fine. If the LED keeps flashing after this time, the device is not working properly. Contact
babyTEL for assistance.
19.When I enter a URL or IP address, I get a time-out error or am prompted to retry.
•
Check if other PCs work. If they do, ensure that your workstation’s IP settings are correct (IP Address,
Subnet Mask, Default Gateway, and DNS). Restart the computer that is having a problem.
•
If the PCs are configured correctly, but still not working, check the Router. Ensure that it is connected and
powered on. Connect to it and check its settings. (If you cannot connect to it, check the LAN and power
connections.)
•
If the Router is configured correctly, check your Internet connection (DSL/cable modem, etc.) to see if it is
working correctly. You can remove the Router to verify a direct connection.
•
Manually configure the TCP/IP settings with a DNS address provided by your ISP.
•
Make sure that your browser is set to connect directly and that any dial-up is disabled. For Internet
Explorer, click
Tools
,
Internet Options
, and then the
Connection
tab. Make sure that Internet Explorer is
set to
Never dial a connection
. For Netscape Navigator, click

Frequently Asked Questions
Wireless-G Broadband Router with 2 Phone Ports
What is the maximum number of IP addresses that the Router will support?
The Router will support up to 253 IP addresses.
Is IPSec Pass-Through supported by the Router?
Yes, it is a built-in feature that the Router automatically enables.
Where is the Router installed on the network?
In a typical environment, the Router is installed between the cable/DSL modem and the LAN.
Plug the Router into
the cable/DSL modem’s Ethernet port.
Does the Router support IPX or AppleTalk?
No. TCP/IP is the only protocol standard for the Internet and has become the global standard for communications.
IPX, a NetWare communications protocol used only to route messages from one node to another, and AppleTalk,
a communications protocol used on Apple and Macintosh networks, can be used for LAN to LAN connections, but
those protocols cannot connect from the Internet to a LAN.
Does the Internet connection of the Router support 100Mbps Ethernet?
The Router’s current hardware design supports up to 100Mbps Ethernet on its Internet port; however, the Internet
connection speed will vary depending on the speed of your broadband connection. The Router also supports
100Mbps over the auto-sensing Fast Ethernet 10/100 switch on the LAN side of the Router.
What is Network Address Translation and what is it used for?
Network Address Translation (NAT) translates multiple IP addresses on the private LAN to one public address that
is sent out to the Internet. This adds a level of security since the address of a PC connected to the private LAN is
never transmitted on the Internet. Furthermore, NAT allows the Router to be used with low cost Internet
accounts, such as DSL or cable modems, when only one TCP/IP address is provided by the ISP. The user may
have many private addresses behind this single address provided by the ISP.
Does the Router support any operating system other than Windows 98SE, Windows Millennium,
Windows 2000, or Windows XP?
Yes, but Linksys does not, at this time, provide technical support for setup, configuration or troubleshooting of
any non-Windows operating systems.
Does the Router support ICQ send file?
Yes, with the following fix: click ICQ menu -> preference -> connections tab->, and check I am behind a firewall
or proxy. Then set the firewall time-out to 80 seconds in the firewall setting. The Internet user can then send a file
to a user behind the Router.

Frequently Asked Questions
Wireless-G Broadband Router with 2 Phone Ports
I set up an Unreal Tournament Server, but others on the LAN cannot join. What do I need to do?
If you have a dedicated Unreal Tournament server running, you need to create a static IP for each of the LAN
computers and forward ports 7777, 7778, 7779, 7780, 7781, and 27900 to the IP address of the server. You can
also use a port forwarding range of 7777 ~ 27900. If you want to use the UT Server Admin, forward another port.
(Port 8080 usually works well but is used for remote admin. You may have to disable this.) Then in the
[UWeb.WebServer] section of the server.ini file, set the ListenPort to 8080 (to match the mapped port above) and
ServerName to the IP assigned to the Router from your ISP.
Can multiple gamers on the LAN get on one game server and play simultaneously with just one public IP
address?
It depends on which network game or what kind of game server you are using.
For example, Unreal Tournament
supports multi-login with one public IP.
How do I get Half-Life: Team Fortress to work with the Router?
The default client port for Half-Life is 27005.
The computers on your LAN need to have “+clientport 2700x”
added to the HL shortcut command line; the x would be 6, 7, 8, and on up. This lets multiple computers connect
to the same server. One problem: Version 1.0.1.6 won’t let multiple computers with the same CD key connect at
the same time, even if on the same LAN (not a problem with 1.0.1.3).
As far as hosting games, the HL server does
not need to be in the DMZ. Just forward port 27015 to the local IP address of the server computer.
How can I block corrupted FTP downloads?
If you are experiencing corrupted files when you download a file with your FTP client, try using another FTP
program.
The web page hangs; downloads are corrupt, or nothing but junk characters are being displayed on the
screen. What do I need to do?
Force your Ethernet adapter to 10Mbps or half duplex mode, and turn off the “Auto-negotiate” feature of your
Ethernet adapter as a temporary measure. (Please look at the Network Control Panel in your Ethernet adapter’s
Advanced Properties tab.) Make sure that your proxy setting is disabled in the browser. Check our website at
www.linksys.com for more information.
If all else fails in the installation, what can I do?
Reboot the system. Please refer to the rebooting procedures in the FAQ section of the babyTEL website.
How will I be notified of new Router firmware upgrades?
babyTEL upgrades the firmware remotely and automatically, when needed. babyTEL will notify you by email
prior to an update.

Frequently Asked Questions
Wireless-G Broadband Router with 2 Phone Ports
Will the Router function in a Macintosh environment?
Yes, but the Router’s setup pages are accessible only through Internet Explorer 4.0 or Netscape Navigator 4.0 or
higher for Macintosh.
I am not able to get the web configuration screen for the Router.
What can I do?
You may have to remove the proxy settings on your Internet browser, e.g., Netscape Navigator or Internet
Explorer.
Or remove the dial-up settings on your browser.
Check with your browser documentation, and make
sure that your browser is set to connect directly and that any dial-up is disabled. Make sure that your browser is
set to connect directly and that any dial-up is disabled. For Internet Explorer, click Tools, Internet Options, and
then the Connection tab. Make sure that Internet Explorer is set to Never dial a connection. For Netscape
Navigator, click Edit, Preferences, Advanced, and Proxy. Make sure that Netscape Navigator is set to Direct
connection to the Internet.
What is DMZ Hosting?
Demilitarized Zone (DMZ) allows one IP address (computer) to be exposed to the Internet. Some applications
require multiple TCP/IP ports to be open.
It is recommended that you set your computer with a static IP if you
want to use DMZ Hosting. To get the LAN IP address, see “Appendix E: Finding the MAC Address and IP Address
for Your Ethernet Adapter.”
If DMZ Hosting is used, does the exposed user share the public IP with the Router?
No.
Does the Router pass PPTP packets or actively route PPTP sessions?
The Router allows PPTP packets to pass through.
Is the Router cross-platform compatible?
Any platform that supports Ethernet and TCP/IP is compatible with the Router.
How many ports can be simultaneously forwarded?
Theoretically, the Router can establish 520 sessions at the same time, but you can only forward 10 ranges of
ports.
What are the advanced features of the Router?
The Router’s advanced features include Advanced Wireless settings, Filters, Port Forwarding, Routing, and DDNS.
